596697 divided by 80 
The aim is to understand the frequency of 80 in 596697.

On to step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 80

Step 2:
59 divided by 80 is 0 with a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Include the next digit (6) from the dividend after 59, then repeat: 596 / 80

Moving on to step 3:
80 can be fit into 596 7 times, resulting in a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 560 from 596 and we're left with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 80

Moving on to step 4:
80 can be fit into 366 4 times, resulting in a remainder of 46.
The next digit of our result is 4. 
Result so far: 74.0
The remainder is 46 after subtracting 320 from 366.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 80

Advancing to step 5:
The number 80 fits into 469 5 times, leaving a remainder of 69.
The number 5 becomes the next digit in our result. 
Result so far: 745.0
Deduct 400 from 469 and we're left with 69.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 80

Going ahead to step 6:
When dividing 697 by 80, we get 8 with a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 7458.0
Deduct 640 from 697 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
570 divided by 80 is 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 7458.7
Deduct 560 from 570 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 80 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 7458.71
Subtracting 80 from 100 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 7458.712
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7458.7125
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7458.7125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7458.7125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 7458.7125, with a leftover of 0.0.
